*4.6. Weight Loss Measurement*

The coated and control fresh-cut sweet purple potatoes were individually weighed using a digital laboratory scale (Mettler Toledo, CH/PL 3002) at each data collection interval. The weight loss was calculated as follows:

$$\text{Weight loss } (\%) = \left[ \frac{\text{w}\_{\text{in}} - \text{w}\_{\text{fin}}}{\text{w}\_{\text{in}}} \right] \times 100 \tag{2}$$

where win and wfin represent the initial and the final weight, respectively, measured at a particular storage interval.
